Looking at the data Yakima has about double the U.S. average crime.
It's racial mix is heavily "hispanic" (close to 50%)... Wages are much lower than the rest of Washington state.
I would not recommend it at all. My wife lived in Seattle and Vanco (Ca) for many years. Low income, gangs, poor tax base. Per capita crime is top decile, or was a few years ago.
I wasn't. I was stating that she knows the area and its problems. She is from the Pac-NW.
